TEXTURE COMPRESSION METHOD AND TEXTURE COMPRESSION APPARATUS, AND TEXTURE DECOMPRESSION METHOD AND TEXTURE DECOMPRESSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a texture compression method and a texture compression apparatus, and a texture decompression method and a texture decompression apparatus.SOLUTION: There are provided a texture compression method and a texture compression apparatus for compressing partial color information of a texture block in which all colors included in the texture block cannot be reproduced by a predetermined number of compression bits so as to be stored in a compression data bit of a texture block capable of reproducing all colors included in the texture block by a smaller number of bits than the predetermined number of compression bits, on the basis of a color distribution of each texture block. There are also provided a texture decompression method and a texture decompression apparatus corresponding thereto.SELECTED DRAWING: Figure 4
